This rather bleak, institutional image is well-taken. Perhaps a figure, somewhere or other would help to relieve that aspect of it..Although, perhaps that is what you wanted to convey.
I love the effect you have used here. The composition here is quite strong. I can't really think of anything to improve the shot at this moment. By the way,t eh back floor really adds to the quality of the image.
Orange chairs, ....yes and in focus and the light is okay......but there is no point of interest for the viewer. Maybe a nude man in the window....a flower on the table..a vase, a coke can.....something to cause the viewer to say...ahhh wow!!
